Abstract
INTRODUCTION End-stage kidney disease (ESKD) is an established risk factor for chronic limb-threatening ischemia (CLTI). Procedural location for ESKD patients has not been well described. This study aims to examine variation in index procedural location in ESKD versus non-ESKD patients undergoing peripheral vascular intervention for CLTI and identify preoperative risk factors for tibial interventions. METHODS Chronic limb-threatening ischemia (CLTI) patients were identified in the Vascular Quality Initiative (VQI) peripheral vascular intervention dataset. Patient demographics and comorbidities were compared between patients with and without ESKD and those undergoing index tibial versus nontibial interventions. A multivariable logistic regression evaluating risk factors for tibial intervention was conducted. RESULTS A total of 23,480 procedures were performed on CLTI patients with 13.6% (n = 3154) with ESKD. End-stage kidney disease (ESKD) patients were younger (66.56 ± 11.68 versus 71.66 ± 12.09 y old, P = 0.019), more often Black (40.6 versus 18.6%, P < 0.001), male (61.2 versus 56.5%, P < 0.001), and diabetic (81.8 versus 60.0%, P < 0.001) than non-ESKD patients. Patients undergoing index tibial interventions had higher rates of ESKD (19.4 versus 10.6%, P < 0.001) and diabetes (73.4 versus 57.5%, P < 0.001) and lower rates of smoking (49.9 versus 73.0%, P < 0.001) than patients with nontibial interventions. ESKD (odds ratio (OR) 1.67, 95% confidence interval (CI) 1.52-1.86, P < 0.001), Black race (OR 1.19, 95% CI 1.09-1.30, P < 0.001), and diabetes (OR 1.82, 95% CI 1.71-2.00, P < 0.001) were risk factors for tibial intervention. CONCLUSIONS Patients with ESKD and CLTI have higher rates of diabetes and tibial disease and lower rates of smoking than non-ESKD patients. Tibial disease was associated with ESKD, diabetes, and Black race.

Differences in Long-Term Outcomes in End-Stage Kidney Disease Patients with Chronic Limb-Threatening Ischemia. Ann Vasc Surg 2023; 95:162-168. [PMID: 37225013 PMCID: PMC10799672 DOI: 10.1016/j.avsg.2023.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 05/05/2023] [Accepted: 05/07/2023] [Indexed: 05/26/2023]
Abstract
BACKGROUND End-stage kidney disease (ESKD) is a risk factor for peripheral arterial disease and major adverse limb events following infra-inguinal bypass. Despite comprising an important patient population, ESKD patients are rarely analyzed as a subgroup and are underrepresented in vascular surgery guidelines. This study aims to compare the long-term outcomes of patients with and without ESKD undergoing endovascular peripheral vascular intervention (PVI) for chronic limb-threatening ischemia (CLTI). METHODS CLTI patients with and without ESKD from 2007-2020 were identified in the Vascular Quality Initiative PVI dataset. Patients with prior bilateral interventions were excluded. Patients undergoing femoral-popliteal and tibial interventions were included. Mortality, reintervention, amputation, and occlusion rates at 21 months following intervention were examined. Statistical analyses were completed with the t-test, chi-square, and Kaplan-Meier curves. RESULTS The ESKD cohort was younger (66.4 ± 11.8 vs. 71.6 ± 12.1 years, P < 0.001) with higher rates of diabetes (82.2 vs. 60.9%, P < 0.001) the non-ESKD cohort. Long-term follow-up was available for 58.4% (N = 2,128 procedures) of ESKD patients and 60.8% (N = 13,075 procedures) of non-ESKD patients. At 21 months, ESKD patients had a higher mortality (41.7 vs. 17.4%, P < 0.001) and a higher amputation rate (22.3 vs. 7.1%, P < 0.001); however, they had a lower reintervention rate (13.2 vs. 24.6%, P < 0.001). CONCLUSIONS CLTI patients with ESKD have worse long-term outcomes at 2 years following PVI than non-ESKD patients. Mortality and amputation are higher with ESKD, while the reintervention rate is lower. Development of guidelines within the ESKD population has the potential to improve limb salvage.

Abstract
PURPOSE Digital amputation is a commonly performed procedure for infection and necrosis in patients with diabetes, peripheral vascular disease (PVD), and on dialysis. There is a lack of data regarding prognosis for revision amputation and mortality following digital amputation in these patients. METHODS All digital amputations over 10-year period (2008-2018) at a single center were reviewed. There were 484 amputations in 360 patients, among which 358 were performed for trauma (reference sample) and 126 for infection or necrosis (sample of interest). Patient death and revision were determined from National Vital Statistics System and medical records. Propensity score matching was performed to compare groups. Data were then compared to the Social Security Administration Actuarial Life Table for 2015 to determine age-matched expected mortality. RESULTS The 2-year revision rate was 34% for amputations performed for infection or necrosis, compared to 15% for amputations due to trauma. For amputations performed for infection or necrosis, the revision rate was 47.7% when diabetes, PVD, and dialysis were present. Among all patients with infection or necrosis (n = 104) undergoing a digital amputation, overall survival at 2, 5, and 10 years was 79.4%, 57.3%, and 17.5%, respectively, which represented a 3.2-fold increased risk of death compared to controls. (hazard ratio, 3.19; 95% confidence interval, 1.47-6.93). For amputations due to trauma, mortality was no different from that in the age-matched general population. CONCLUSIONS Mortality and revision risk are high for patients requiring a digital amputation for infection or necrosis and are further increased with medical comorbidities. Hand surgeons should consider the prognostic implications of these data when counseling patients. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
OBJECTIVE People with diabetes who are on haemodialysis (HD) are at a high risk of diabetic foot infections (DFI) and related complications. We explored the value of treating DFI with intravenous (IV) antibiotics during HD. METHOD This was an observational study of consecutively treated patients with DFIs with IV antibiotics during HD. Data collected included baseline characteristics, IV antibiotics used, details of multidisciplinary interventions and DFI treatment outcome. RESULTS A cohort of 11 patients, mean (±standard deviation) age 62.4±12.7 years, had 15 episodes of treatment with IV antibiotics during HD. Of the patients, six (54.5%) were male and nine (81.8%) had type 2 diabetes. The estimated mean glomerular filtration rate (eGFR) was 11.4±3.9ml/minute. All patients had infected foot ulceration, soft tissue infection, six (54.5%) patients had osteomyelitis, and two (18.2%) had wet gangrene. The commonest IV antibiotic used was vancomycin (10/15 episodes, 66.7%). Other IV antibiotics used were daptomycin and meropenem. In three episodes, oral ciprofloxacin was used with IV antibiotics. The mean duration of antibiotic treatment was 9.2±4.9 weeks. Of the episodes, 11 (73.3%) were treated successfully with IV antibiotics alone and two (13.3%) episodes required minor surgical debridement/amputation. Some 10 (90.9%) members of the cohort had peripheral arterial disease and of those, five (50%) underwent angioplasty during IV antibiotic treatment. CONCLUSION HD provides a good opportunity for treatment with IV antibiotics in DFI. This mode of administration of IV antibiotics, along with multidisciplinary intervention, is associated with ulcer healing and resolution of infection in over three-quarters of patients with DFI. DECLARATION OF INTEREST The authors have no conflicts of interest to declare.

Abstract
Vascular complications are the leading cause of morbidity and mortality among patients with type 2 diabetes mellitus (T2DM). These vascular abnormalities result in a chronic hyperglycemic state, which influences many signaling molecular pathways that initially lead to increased oxidative stress, increased inflammation, and endothelial dysfunction, leading to both microvascular and macrovascular complications. Endothelial dysfunction represents the initial stage in both types of vascular complications; it represents "mandatory damage" in the development of microvascular complications and only "introductory damage" in the development of macrovascular complications. Increasing scientific evidence has revealed an important role of the Wnt pathway in the pathophysiology of the vascular wall. It is well known that the Wnt pathway is altered in patients with T2DM. This review aims to be an update of the current literature related to the Wnt pathway molecules that are altered in patients with T2DM, which may also be the cause of damage to the vasculature. Both microvascular complications (retinopathy, nephropathy, and neuropathy) and macrovascular complications (coronary artery disease, cerebrovascular disease, and peripheral arterial disease) are analyzed. This review aims to concisely concentrate all the evidence to facilitate the view on the vascular involvement of the Wnt pathway and its components by highlighting the importance of exploring possible therapeutic strategy for patients with T2DM who develop vascular pathologies.

Abstract
OBJECTIVE To describe the angiographic characteristics of peripheral arterial disease (PAD) in persons with diabetic foot ulcers (DFUs) on dialysis treatment. METHOD The study is a retrospective analysis of patients with DFUs and PAD who had been referred to our diabetic foot clinic. All patients had been managed by a pre-set limb salvage protocol including revascularisation of the affected limb. Arterial lesions (stenosis between 50-99% and occlusions) were retrospectively evaluated through angiogram analysis. According to the presence or not of dialysis, patients were divided into two patient groups: renal-diabetic foot (RDF) and diabetic foot (DF). Distribution of PAD and immediate revascularisation outcome (technical revascularisation outcome) for RDF and DF were separately reported and compared. RESULTS The sample included 239 patients: mean age was 71.8 years; 72.4% were male; 87.4% had type 2 diabetes; mean diabetes duration was 21.4 years; and the mean HbA1c was 63±22mmol/mol. The RDF group compared with the DF group reported higher numbers of vessels affected (n=5±1.6 versus 3.9±1.5, respectively, p<0.0001), greater involvement of the superficial femoral artery (90.2% versus 75.8%, respectively, p=0.003), the tibial-peroneal trunk (53.7% versus 25.5%, respectively, p=0.01), the anterior tibial artery (93.9% versus 80.9%, respectively, p=0.03) and below-the-ankle (BTA) arteries (70.7% versus 35.7%, respectively, p=0.0001). The RDF group showed a higher rate of revascularisation failure in comparison to DF patients (43.9% versus 15.3%, respectively, p<0.0001). BTA arterial disease (odds ratio 9.5; 95% Confidence Interval: 3.5-25.4; p=0.0001) resulted as the only independent predictor of revascularisation failure. CONCLUSION In this study, RDF patients showed a widespread distribution of arterial lesions with a higher involvement of foot arteries in comparison with DF patients. BTA arterial disease was found to be an independent predictor of revascularisation failure.

Abstract
OBJECTIVES This study aims to assess the use of drug-coated balloon (DCB) in a large patient population under real-world conditions and, specifically, analyse the impact of diabetes mellitus on long term outcomes following DCB utilisation. METHODS BIOLUX P-III is a prospective, international, multicentre, registry that was conducted at 41 centres. The present study is a 24-month subgroup analysis of patients with diabetes mellitus having infrainguinal lesions treated with the Passeo-18 Lux DCB. The primary endpoints were freedom from major adverse events (MAEs) within 6 months of intervention and freedom from clinically driven target lesion revascularisation (CD-TLR) within 12 months of intervention. RESULTS Of the 882 patients in the registry, 418 had diabetes (516 lesions). Most diabetics had concomitant hypertension (88.8%) and hyperlipidaemia (70.3%). Insulin dependence was observed in 48.8% of diabetics. Moreover, smoking (62.2%) and chronic renal insufficiency (41.9%) were also found to be common in this cohort. Chronic limb threatening ischemia (Rutherford class ≥4) was present in 53.1% of all patients. 22.9% of lesions were infrapopliteal, while 22.5% of lesions were treated for in-stent restenosis. The mean target lesion length was 85.6 ± 73.2 mm, and 79.4% of lesions were calcified (of which 17.9% were heavily calcified). Overall, device success was 99.7%. Freedom from MAEs was 90.5% (95% confidence interval (95% CI): 87.2-93.0) at 6 months, 85.4% (95% CI: 81.5-88.6) at 12 months and 80% (95% CI: 75.5-83.8) at 24 months. Freedom from CD-TLR was 95.9% (95% CI: 93.8-97.4), 91.6% (95% CI: 88.7-93.8), and 87.1% (95% CI: 83.5-89.9) at 6, 12, and 24 months, respectively. All-cause mortality at 24 months in diabetics was 16.0% (95% CI: 12.6-20.2), and major target limb amputation was 6.1% (95% CI: 4.1-8.9), which was significantly higher than in non-diabetics (8.4% (95% CI: 6.0-11.6), P = 0.0005 and 1.2% (95% CI: 0.5-2.9), P <0.0001, respectively). At 24 months, 82.0% of patients had improved by ≥1 Rutherford class. CONCLUSION Treatment of a real-world diabetic patient population with the Passeo-18 Lux DCB resulted in high efficacy and low complication rates, despite the fact that diabetic patients usually suffer from a multitude of concomitant comorbidities.

Abstract
A growing, but poorly defined subset of patients with chronic limb-threatening ischemia (CLTI) have "no option" for revascularization. One notable subgroup includes patients with severe ischemia and advanced pedal artery occlusive disease, termed "desert foot," who are at high risk for major amputation due to a lack of conventional revascularization options. Although new therapies are being developed for no-option patients with desert foot anatomy, this subgroup and the broader group of no-option patients are not well defined, limiting the ability to evaluate outcomes. Based on a systematic review, a classification of the no-option CLTI patient was constructed for use in clinical practice and studies. Several no-option conditions were identified, including type I-severe and pedal occlusive disease (desert foot anatomy) for which there is no accepted method of repair; type II-lack of suitable venous conduit for bypass in the setting of an acceptable target for bypass; type III-extensive tissue loss with exposure of vital structures that renders salvage impossible; type IV-advanced medical comorbidities for which available revascularization options would pose a prohibitive risk; and type V-presence of a nonfunctional limb. While type I and type II patients may have no option for revascularization, type III and type V patients have wounds, infection, comorbidities, or functional status that may leave them with few options for revascularization. As treatment strategies continue to evolve and novel methods of revascularization are developed, the ability to identify no-option patients in a standardized fashion will aid in treatment selection and assessment of outcomes.

[PMID: 32651160 DOI: 10.1016/j.carrev.2020.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Accepted: 06/08/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND/PURPOSE Although the incidence of peripheral artery disease (PAD) and amputations is higher in Native Americans (NA) than Caucasians, the study of revascularization NA is limited, resulting in their under representation in clinical studies. Orbital atherectomy (OA) is widely utilized for endovascular revascularization of significantly calcified peripheral arteries and has been shown to improve limb salvage rates. METHODS/MATERIALS A cohort of 74 consecutive PAD subjects undergoing OA treatment was retrospectively analyzed via Kaplan Meier (KM) and Propensity Score Matched (PSM) analysis. RESULTS A significant proportion of the subjects were NA (16.2%). Compared to the non-NA, the NA had higher numerical baseline rates of wounds, dialysis, chronic kidney disease (CKD), and critical limb ischemia, but were numerically less likely to smoke and had similar rates of diabetes. There were very high rates of severe calcification (100% vs. 87%) and pre-procedure diameter stenosis (99% vs. 95%) in both groups. The NA and non-NA had good angiographic outcomes, resulting in low rates of post-procedure residual diameter stenosis (10% vs. 11%). Lastly, KM analysis indicated high freedom from amputation in both groups at 1 year (89% vs. 95%), as well as in the PSM subjects (89% vs. 100%). CONCLUSIONS Despite numerically higher rates of co-morbidities at baseline (e.g., CKD, dialysis, and presence of non-healing wounds), the NA underwent successful revascularization with OA, resulting in high freedom from amputation at 1-year. Given the small sample size of NA, these results may not be generalizable-thus, larger studies on NA are warranted.

Abstract
Given the increased incidence and prevalence of ESKD (end-stage kidney disease) attributed to diabetes mellitus, it is important to consider the physiological and global sociodemographic factors that give rise to unique challenges in providing excellent care to this population. The individual with diabetes and ESKD faces alterations of glucose homeostasis that require close therapeutic attention, as well as the consideration of safe and effective means of maintaining glycemic control. Implementation of routine monitoring of blood glucose and thoughtful alteration of the individual's hypoglycemic drug regimen must be employed to reduce the risk of neurological, cardiovascular, and diabetes-specific complications that may arise as a result of ESKD. Titration of insulin therapy may become quite challenging, as kidney replacement therapy often significantly impacts insulin requirements. New medications have significantly improved the ability of the clinician to provide effective therapies for the management of diabetes, but have also raised an equal amount of uncertainty with respect to their safety and efficacy in the ESKD population. Additionally, the clinician must consider the challenges related to the delivery of kidney replacement therapy, and how inter-modality differences may impact glycemic control, diabetes, and ESKD-related complications, and issues surrounding dialysis vascular access creation.

Anichini R, Brocco E, Caravaggi CM, Da Ros R, Giurato L, Izzo V, Meloni M, Uccioli L. Physician experts in diabetes are natural team leaders for managing diabetic patients with foot complications. A position statement from the Italian diabetic foot study group. Nutr Metab Cardiovasc Dis 2020; 30:167-178. [PMID: 31848052 DOI: 10.1016/j.numecd.2019.11.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 11/16/2019] [Accepted: 11/18/2019] [Indexed: 12/16/2022]
Abstract
Diabetic foot syndrome (DFS) is a complex disease. The best outcomes are reported with the multi-disciplinary team (MDT) approach, where each member works collaboratively according to his/her expertise. However, which health provider should act as the team leader (TL) has not been determined. The TL should be familiar with the management of diabetes, related complications and comorbidities. He/she should be able to diagnose and manage foot infections, including prompt surgical treatment of local lesions, such as abscesses or phlegmons, in an emergent way in the first meeting with the patient. According to the Organization for Economic Co-operation and Development (OECD) reports, Italy is one of countries with a low amputation rate in diabetic patients. Many factors might have contributed to this result, including 1)the special attention directed to diabetes by the public health system, which has defined diabetes as a "protected disease", and accordingly, offers diabetic patients, at no charge, the best specialist care, including specific devices, and 2)the presence of a network of diabetic foot (DF) clinics managed by diabetologists with medical and surgical expertise. The health care providers all share a "patient centred model" of care, for which they use their internal medicine background and skills in podiatric surgery to manage acute or chronic needs in a timely manner. Therefore, according to Italian experiences, which are fully reported in this document, we believe that only a skilled diabetologist/endocrinologist should act as a TL. Courses and university master's degree programmes focused on DF should guarantee specific training for physicians to become a TL.

Abstract
AIMS Diabetic foot syndrome (DFS) increases the risk for atherosclerotic cardiovascular disease (ASCVD), chronic kidney disease (CKD), or mortality. The present study aims at ascertaining whether such DFS-related excess risk differs between genders, retrospectively investigating a population with diabetes from Tuscany, Italy, followed-up for 6 years (2011-2016). METHODS People with diabetes living in Tuscany on January 1st 2011 identified by administrative databases, were divided by baseline history of prior DFS hospitalizations, stratified by presence/absence of peripheral vascular disease and evaluating, by Cox regression analysis, whether adjusted DFS-related excess risk of incident ASCVD, CKD or mortality differed between genders. RESULTS In an overall population of 165,650 subjects with diabetes (81,829M/83,821F), basal prevalence of DFS was twice higher among males, who were moreover at a significantly greater risk of all considered outcomes along the 6-year period. On the contrary, baseline DFS significantly increased the hospitalization risk for ASCVD, CKD and mortality equally or at a slightly greater extent in females, while the risk for stroke was significantly associated with DFS only among females (HR: 1.622 (1.314-1.980); p = 0.0001 vs. HR: 1.132 (0.955-1.332); p = NS). This finding was even reinforced in non-vascular DFS, which was associated with a significant raised risk for stroke, heart failure or mortality exclusively in females. CONCLUSIONS In this population, DFS prevalence and overall risk for ASCVD, CKD or mortality were significantly higher among males. Baseline co-presence of DFS, however, conferred a similar adjusted risk for all these outcomes between genders, and in case of non-vascular DFS the risk was significantly increased only among females.

Single nucleotide polymorphisms in cytokine/chemokine genes are associated with severe infection, ulcer grade and amputation in diabetic foot ulcer. Int J Biol Macromol 2018; 118:1995-2000.

Abstract
Compared to other complications the genetics of diabetic foot ulcer is poorly studied. The Interleukin (IL)-6 (-174G > C/rs1800795), Tumor Necrosis Factor (TNF)-α (-308G > A/rs1800629) and (-238G > A/rs361525) and Stromal cell Derived Factor (SDF)-1 (+801G > A/rs1801157) are well characterized single nucleotide polymorphisms (SNPs) which were previously shown to be associated with Diabetic Foot Ulcer (DFU). In the present study, we looked at the association of these SNPs with foot microbial infection, Wagner's ulcer grade and treatment procedure, along with serum levels of these cytokines (intermediate phenotype) and other serum biomarkers (adiponectin, leptin, CRP and HOMA-IR) in subjects with DFU. Subjects with DFU (n = 270) were genotyped by PCR-RFLP and the serum levels of IL-6, TNF-α and SDF-1 were determined by ELISA. Microbial infections were determined by standard microbiological methods. Ulcer grade and treatment procedures were recorded. IL-6 (-174G > C), TNF-α (-308G > A) and SDF-1 (+801G > A) SNPs were associated with severe microbial infections. TNF-α (-308G > A) and (-238G > A) SNPs were associated with severe ulcer grades. SDF-1 (+801G > A) SNP was associated with major amputation even after adjusting for confounding variables. Identification of these SNPs in DFU subjects would help in identifying high risk individuals who need better treatment care.

Abstract
Introduction: Antibiotic treatment (antibiotherapy) of diabetic foot ulcers has been proven to have toxic effect on renal function.
Objectives: This study aimed to evaluate renal function in patients with diabetic foot infection.
Patients and Methods: This cross-sectional retrospective study was performed on 142 patients with diabetic foot ulcers hospitalized in Shahid Yahyanejad hospital of Babol during 2013. After referring to profile of the patients, they were assigned to participate in two groups: group A consisted of patients receiving antibiotics with a low risk renal toxicity and patients who received antibiotics with a higher risk of renal toxicity were placed in group B. Glomerular filtration rate (GFR) was measured and calculated based on serum concentration of creatinine and Cockcroft-Gault equation. Data was analyzed using SPSS version 20.0 with chi-square, t test and paired t tests.
Results: Group A consisted of 74 patients (52.1%) and 68 patients (47.9%) participated in group B. GFRs before and after antibiotherapy were 64.73±33.87 cc/min and 59.10±30.51 cc/min, respectively (P=0.004). In group B, GFR decreased significantly after antibiotherapy (P=0.002).
Conclusion: According to the present study, renal function decreased after antibiotherapy and in patients who received antibiotics with higher nephrotoxicity rate, the rate of this decline was higher.

Abstract
The estimated prevalence of diabetes is 9.78% in Taiwan. The lifetime risk for patients with diabetes to have foot ulcers might be as high as 25%. About 15% of these patients require major limb amputation because of ischemia and infection. Peripheral artery disease is still a major problem involved in diabetic foot disease and the cause for major amputation despite an increase in the prevalence of revascularization surgery and new revascularization techniques over the past 20 years. We investigated the major limb amputation rates in patients with diabetic foot and critical limb ischemia who had undergone revascularization surgery in our hospital. The records of 42 patients who had undergone revascularization surgery for diabetic foot were retrospectively reviewed. Nineteen patients (45%) required major limb amputation despite revascularization. The affected limbs of only 15 patients (36%) were salvaged. Four patients died soon after surgery because of comorbidities, and another 4 were lost to follow-up. Two patients died from procedure-related sepsis, and overall perioperative mortality was 4.8%. Ten predictive risk factors (duration of diabetes, history of smoking, coronary artery disease, congestive heart failure, cerebral vascular accident, contralateral amputation, end-stage renal disease, fever episode, wound infection severity score, and arterial obstruction level) were included for analysis. Although none was significant, long-duration diabetes (OR: 1.13), end-stage renal disease (OR: 10.02), wound infection (OR: 1.56), and infrapopliteal lesions (OR: 3.00) tended to be unfavorable predictive risk factors of limb amputation. Revascularization surgery is still potentially beneficial for these patients--eg, it decreases the contralateral limb amputation rate by 7.5%--if done early in high-risk patients.

Abstract
Purpose The changes of the risk of peripheral arterial disease (PAD) in patients with end-stage renal disease after parathyroidectomy are scant. Methods We used a nationwide health insurance claims database to select all dialysis-dependent patients with end-stage renal disease aged 18 years and older for the study population in 2000 to 2006. Of the patients with end-stage renal disease, we selected 947 patients who had undergone parathyroidectomy as the parathyroidectomy group and frequency matched 3746 patients with end-stage renal disease by sex, age, years since the disease diagnosis, and the year of index date as the non-parathyroidectomy group. We used a multivariate Cox proportional hazards regression analysis with the use of a robust sandwich covariance matrix estimate, accounting for the intra-cluster dependence of hospitals or clinics, to measure the risk of peripheral arterial disease for the parathyroidectomy group compared with the non-parathyroidectomy group after adjusting for sex, age, premium-based income, urbanization, and comorbidity. Results The mean post-op follow-up periods were 5.08 and 4.52 years for the parathyroidectomy and non-parathyroidectomy groups, respectively; the incidence density rate of PAD in the PTX group was 12.26 per 1000 person-years, significantly lower than the data in the non-PTX group (24.09 per 1000 person-years, adjusted HR = 0.66, 95% CI = 0.46–0.94). Conclusion Parathyroidectomy is associated with reduced risk of peripheral arterial disease in patients with end-stage renal disease complicated with severe secondary hyperparathyroidism.

Abstract
AIM To evaluate the outcomes of diabetic dialysis patients with critical limb ischemia and foot ulcer. METHODS The study group included 599 diabetic, 99 dialyzed (Ds) (16.5%) and 500 not dialyzed (NDs) (83%) patients with critical limb ischemia and foot ulcers identified as stage C (ischemia) or D (ischemia plus infection) of Texas Wound Classification. All patients were treated by endovascular revascularization. Outcomes were expressed as healing, major amputation, death and non healing after 12months. The mean follow-up was 15±13months. RESULTS The outcomes of the whole population were: 48.9% healing, 11.3% major amputation, 12.7% death, 27.1 non healing. At the multivariate analysis dialysis was a negative predictor of healing and a positive predictor of major amputation. Outcomes for Ds and NDs were respectively: healing (30.3 vs 52.6%), major amputation (14.4 vs 10.8%), death (21.1 vs 11%) and non-healing (34.2 vs 25.6%) (X=0.0004). Amputation occurred earlier in Ds than in NDs. According to the multivariate analysis in Ds ischemic heart disease and lower ΔTcPO2 were negative predictors for healing. Successful revascularization was a negative predictor for major amputation. HDL and carotid artery disease were predictive factors of death among NDs. Among Ds high blood pressure values were the only predictor of amputation while no variable resulted predictive of healing or death. CONCLUSIONS Our study shows that our limb salvage protocol ensures a good rate of limb salvage in Ds even if they have a higher risk of amputation and death compared to NDs.

Abstract
OBJECTIVE Analysis of in-hospital outcomes in patients treated for critical limb ischemia (CLI) and end-stage renal disease (ESRD) compared to CLI patients with normal renal function. METHODS A subgroup analysis of the German CRITISCH registry, a prospective multicenter registry, assessing the first-line treatment strategies in CLI patients in 27 vascular centers in Germany was performed. The study cohort was divided into ESRD patients (n = 102) and patients with normal renal function (n = 674; glomerular filtration rate >60/mL/min/1.73 m(2)). The following first-line treatment strategies were assessed: endovascular therapy (EVT), bypass surgery, patch plasty, and no vascular intervention (conservative treatment, primary amputation). Uni- and multivariate analyses were performed to identify differences between groups as to six end points: amputation or death (composite end point), amputation, death, hemodynamic failure, major adverse cardiac and cerebrovascular events, and reintervention. RESULTS Differences between the ESRD and non-ESRD group were found regarding the applied first-line therapy (P = .016): The first-line treatment strategies in ESRD patients were EVT in 64% (n = 65), bypass surgery in 13% (n = 13), patch plasty in 11% (n = 11), and no vascular intervention in 13% (n = 13). In non-ESRD patients, EVT was applied in 48% (n = 326), bypass surgery in 27% (n = 185), patch plasty in 13% (n = 86), and no vascular intervention in 11% (n = 77). For ESRD patients, a noticeably increased risk of the composite end point (odds ratio [OR], 2.62; 95% confidence interval [CI], 1.19-5.79; P = .017), amputation (OR, 3.14; 95% CI, 1.35-7.31; P = .008), and hemodynamic failure (OR, 2.19; 95% CI, 1.19-4.04; P = .012) was observed. CONCLUSIONS CLI patients on dialysis represent a challenging cohort prone to in-hospital death, amputation, and hemodynamic failure. Two-thirds of these high-risk patients are treated with EVT. Present data suggest that this modality is generally considered as the most favorable treatment option in this patient subgroup.

Abstract
PURPOSE To compare the 5-year survival rate of patients on dialysis requiring an upper extremity amputation with those who did not require such surgery and to analyze whether such an amputation was prognostic for mortality. METHODS The medical records of 20 consecutive patients with end-stage renal disease who received upper extremity amputations were reviewed. Control patients (n = 40) were matched based on age, sex, and duration of dialysis treatment. A Kaplan-Meier survival analysis was performed. RESULTS The mean survival time after the index surgery for the surgical group was 4.95 years ± 0.90 years, and the mean survival for the control group was 8.40 years ± 0.61 years. The probability of death (the event) was statistically greater in the surgical group. The overall 5-year survival rates for the surgical and the nonsurgical groups were 35% (7 of 20) and 70% (28 of 40), respectively. Patients with diabetes in the surgical group had a significantly lower 5-year survival rate, a greater number of amputations, and a greater number of wound-healing failures. CONCLUSIONS The 5-year survival rate from the index surgery of the surgical group was half that of the nonsurgical group. Increased mortality may be partially attributed to the poor vascular health of the patient. This analysis may help the hand surgeon to more effectively counsel patients with end-stage renal disease about the prognosis associated with an upper extremity amputation and, more importantly, supports the goal of timely intervention by the multidisciplinary team to optimize care planning and to improve surgical outcomes and quality of life. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic III.

Abstract
Aims The aims of this study were to evaluate the outcomes of treatment among hospitalized patients with diabetic foot ulcers, the risk factors for non-healing ulcers, and the rate of major amputation among Thai patients. Methods A retrospective study of hospitalized diabetic foot patients treated at Theptarin Hospital during the period of 2009–2013. The complete healing rate was assessed at 12 months after admission. Results During the study period, 232 patients (123 males and 109 females) with 262 admissions were included (mean age 65.6 ± 11.9 years, mean duration of diabetes 17.2 ± 9.9 years) with a mean follow-up of 17.5 ± 16.7 months. Major amputations were performed in 4.2% of the patients and peripheral vascular disease (PVD) was a predictive factor (OR 5.25; 95% CI [1.43–19.29]; p-value 0.006). Complete healing (including minor amputations) was achieved in 82.1% of the admissions. Only DFU of the heel was a statistically significant (OR 3.34; 95% CI [1.11–10.24]; p-value 0.041) predictor of non-healing ulcers. Three patients (1.1%) died during hospitalization. Conclusions Management of diabetes-related foot ulcers with a multidisciplinary approach resulted in a limb salvage rate that was greater than 90% and a complete healing rate that was greater than 80%. Successful management of diabetic foot ulcers might be possible in Thailand utilizing this approach.

Abstract
Complete ulcer healing is one of the most important goals of treatment for critical limb ischemia; however, it is still difficult to inform patients of the time to ulcer healing before performing revascularization. The time to ulcer healing has a great impact on the cost of treatment and patient's quality of life. To predict it, the factors that influence delayed ulcer healing should be explored. According to a review of the literature investigating ulcer healing after revascularization, the influential factors can be classified into 5 categories: (1) systemic factors; (2) clinical state of tissue defect; (3) infection; (4) wound management strategy; and (5) revascularization strategy (endovascular or open repair, the angiosome concept). It is also important to ensure sufficient blood supply to predict ulcer healing probability in the individual patient. Several new methodologies, such as measuring tissue circulation around the tissue defect and intraoperative imaging techniques, have been reported. Because the status of ischemic tissue loss and wound healing ability can affect the decision-making process in selecting the revascularization strategy, understanding the many factors that influence ulcer healing after revascularization is indispensable for physicians performing revascularization. Accumulating ulcer healing data via well-designed clinical research can help to establish a new paradigm for the revascularization strategy from the viewpoint of ulcer healing.

Abstract
PURPOSE To assess image quality and diagnostic performance of unenhanced magnetic resonance (MR) angiography with use of flow-sensitive dephasing (FSD)-prepared steady-state free precession (SSFP) of the foot arteries in patients with diabetes. MATERIALS AND METHODS This prospective study was approved by institutional review board. Informed consent was obtained from all subjects. Thirty-two healthy volunteers and 38 diabetic patients who had been scheduled for lower-extremity contrast material-enhanced MR angiography were recruited to undergo unenhanced MR angiography with a 1.5-T MR unit. Image quality and diagnostic accuracy of unenhanced MR angiography in the detection of significant arterial stenosis (≥50%) were assessed by two independent reviewers. Contrast-enhanced MR angiography was used as the reference standard. The difference in the percentage of diagnostic arterial segments at unenhanced MR angiography between healthy volunteers and diabetic patients was evaluated with the McNemar test and generalized estimating equation for correlated data. Signal-to-noise ratio (SNR) and artery-to-muscle contrast-to-noise ratio (CNR) of pedal arteries were measured and compared between the two MR angiography techniques by using the paired t test. RESULTS All subjects successfully underwent unenhanced MR angiography of the foot. Unenhanced MR angiography yielded a high percentage of diagnostic arterial segments in both healthy volunteers (303 of 320 segments, 95%) and patients (341 of 370 segments, 92%), and there was no difference in the percentage between the two populations (P = .195). In patients, the average SNR and CNR at unenhanced MR angiography were higher than those at contrast-enhanced MR angiography (SNR: 90.7 ± 38.1 vs 81.7 ± 34.7, respectively, P = .023; CNR: 85.2 ± 33.2 vs 76.6 ± 33.5, respectively, P = .013). The average sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of unenhanced MR angiography were 88% (35 of 40 segments), 93% (107 of 115 segments), 81% (35 of 43 segments), 96% (107 of 112 segments), and 92% (142 of 155 segments), respectively. Interobserver agreement between the two readers for diagnostic accuracy was good (κ = 0.83). CONCLUSION Unenhanced MR angiography with use of FSD-prepared SSFP allows clear depiction of the foot arterial tree and accurate detection of significant arterial stenosis. The technique has the potential to be a safe and reliable screening tool for the assessment of foot arteries in diabetic patients without the use of gadolinium-based contrast material.

Abstract
Diabetic foot (DF) is a chronic and highly disabling complication of diabetes. The prevalence of peripheral arterial disease (PAD) is high in diabetic patients and, associated or not with peripheral neuropathy (PN), can be found in 50% of cases of DF. It is worth pointing out that the number of major amputations in diabetic patients is still very high. Many PAD diabetic patients are not revascularised due to lack of technical expertise or, even worse, negative beliefs because of poor experience. This despite the progress obtained in the techniques of distal revascularisation that nowadays allow to reopen distal arteries of the leg and foot. Italy has one of the lowest prevalence rates of major amputations in Europe, and has a long tradition in the field of limb salvage by means of an aggressive approach in debridement, antibiotic therapy and distal revascularisation. Therefore, we believe it is appropriate to produce a consensus document concerning the treatment of PAD and limb salvage in diabetic patients, based on the Italian experience in this field, to share with the scientific community.

Abstract
The prevalence of peripheral arterial disease and both traditional and nontraditional vascular risk factors are more common in patients with end-stage renal disease who are undergoing hemodialysis than the general population. Patients undergoing hemodialysis may also be at risk for peripheral arterial disease via nonvascular risk factors and the hemodialysis treatment itself. Unfortunately, because peripheral arterial disease and its risk factors in hemodialysis patients have not been thoroughly ascertained, evaluation of potential treatments has been limited. Given the high potential of morbidity and impaired quality-of-life related to peripheral arterial disease in patients with end-stage renal disease, additional studies are needed to evaluate both quality of life and potential screening for peripheral arterial disease, its risk factors, and treatments to identify areas for improvement in this vulnerable population.

Abstract
OBJECTIVES This study was planned to evaluate the prognostic impact of end-stage renal disease (ESRD) in patients with critical leg ischemia (CLI) undergoing infrainguinal revascularization. MATERIALS AND METHODS 1425 patients who underwent infrainguinal revascularization for CLI were the subjects of the present analysis. Ninety-five patients had ESRD (eGFR < 15 ml/min/m²), and of them 66 (70%) underwent percutaneous transluminal angioplasty and 29 (30%) underwent bypass surgery. RESULTS ESRD patients had significantly lower overall survival (at 3-year, 27.1% vs. 59.7%, p < 0.0001), leg salvage (at 3-year, 57.7% vs. 83.0%, p < 0.0001), and amputation free survival (at 3-year, 16.2% vs. 52.9%, p < 0.0001) than patients with no or less severe renal failure. The difference in survival was even greater between 86 one-to-one propensity matched pairs (at 3-year, 23.1% vs. 67.3%, p < 0.0001). ESRD was an independent predictor of all-cause mortality (RR 2.46, 95%CI 1.85-3.26). Logistic regression showed that age ≥ 75 years was the only independent predictor of 1-year all-cause mortality (OR 4.92, 95%CI 1.32-18.36). Classification and regression tree analysis showed that age ≥ 75 years and, among younger patients, bypass surgery for leg ulcer and gangrene were associated with significantly higher 1-year mortality CONCLUSIONS Lower limb revascularization in patients with CLI and end-stage renal failure is associated with favourable leg salvage. However, these patients have a very poor survival and this may jeopardize any attempt of revascularization. Further studies are needed to identify ESRD patients with acceptable life expectancy and who may benefit from lower limb revascularization.

Abstract
Despite numerous attempts, chronic critical limb ischaemia (CLI) has not been unequivocally defined as yet. Its epidemiology is poorly investigated and its prevalence probably higher than anticipated. It is accompanied by high mortality and morbidity irrespective of the way it is treated. Its management is very expensive. Additionally, the prevailing diabetes epidemic is increasing the need for revascularizations although there is a clear lack of evidence as to when to revascularize an ulcerated diabetic foot. The fast development of endovascular techniques blurs the vision as the window of opportunity for gathering proper evidence keeps narrowing. The notion of endovascular artistry prevails, but attempts to conduct proper studies with clear definitions, strict criteria and appropriate outcome measures in a standardised manner should continue--preferably using propensity scoring if randomised controlled trials are not possible. This review highlights some of the steps leading from art to evidence and illustrates the difficulties encountered along the path. In parallel with this overview, the progress of the treatment for CLI in Finland is described from the perspective of the work concluded at Helsinki University Central Hospital.
